Mobile backhauling shifts up a gear
May 2012
2
Just so you know that we know what we are talking about!
• We are not a mobile operator, but we are the #1 fixed provider for the UK
• We are the market leader for UK mobile backhaul with over 13,000 ethernet
connections and over 78,000 via TDM
• Our ethernet product supports TDM, ATM & DE with a 99.95% availability
And we’re ready for LTE
• IP-VPN capable
• Timing - 1588 live with SyncE in Q3 12/13
• 6 Classes of Service
• Test data proving our network exceeds the LTE RTD & jitter requirements of LTE
• Cell access options of 100Mbps & 1Gbps with 10Gbps planned for 13/14, Switch
site at 1Gbps & 10Gbps readily available
• A cost model that detaches cellsite growth from the core

But it’s not just about arteries, its about the capillaries

• Small Cell Forum (SCF) has grown to 67 operator and 75 vendor members
• Backhaul at the capacity required with right economics is seen as one of the biggest
challenges to deployment of small cells.
• The Special Interest Group will extend the technical work carried out by NGMN Alliance
to :
• understand the deployment scenarios for small cells and scale of deployment
• appreciate the portfolio of backhaul solution available for each scenario
• provide recommendations and identify challenges with each
• The target output is an industry white paper providing insight into backhaul options for
small cells.
BT is chairing the backhaul Special Interest Group in the Small Cell Forum

Small cells will drive the next evolution of backhaul
Rural Urban
Cost effective coverage in
marginal locations
Capacity where it’s needed

A long way from East Garston…
• UK Government is providing £150m to deliver 2/3G voice coverage in rural „not-
spots‟
• LTE out of scope; sparse population and low device penetration
• 80,000 un-served premises
• Some main roads also included
• Procurement running until November 2012; build complete by March 2015
7
• 15% of required macro sites in
England are in „beauty spots‟……
‘Macro only’ solutions can only cover 50,000 of the 80,000 target not-spots. A hybrid macro and small cell solution hits 70,000
• There‟s a good reason why there are no
macro‟s there!
8
Beyond fibre: working with EverythingEverywhere, a shared rural LTE trial with 200 live mobile and fixed wireless customers
Slide 8
• Trial started in September 2011
• 11.6Mbps down 4.7Mbps up typical performance
• External antenna needed in only 20% of cases
• BT also trialling other radio solutions; notably TVWS
9
So what does that mean for rural backhaul ?
• Small cells make economic sense
and environmental sense; shared
small cells even more-so
• Leverage fibre deployment, where
available (more later…)
• Microwave will be critical (1000
connections just for the
Government‟s £150m plan)
• BT has over 8,000 Microwave
links today
• P2MP radio solutions to connect
small cell clusters will be required
10
Government action is also going to accelerate urban small cell thinking
• £150m state aid Urban Broadband Fund
• 20 cities will benefit; first ten already named
• 3 million will benefit from “wireless broadband”
• Initial requirements are fibre for inclusion and economic uplift
• Looking for operators to fund wireless uplift
• Leverage street furniture
• O2 and Westminster example
• Macro sites „getting harder to come by‟
• WiFi and 3/4G

Small cells need to be exactly where the traffic hotspot is, NOT where your backhaul is….

We are leveraging BT’s £2.5bn investment in fibre for small cell backhaul
• FTTC – available today
• FTTP – available today
• FTTP On Demand will deliver up to 330Mbps and will pilot from June, available
from Spring 2013
• We‟ve requested FTTC/P terminated on „non-served premises‟ – street furniture to
you and me!
• Traffic from macro cells and small cells to be delivered via the same point.
• End to end service guaranteed for both types of cells.
13
Comedy and small cells; its all about the timing….
Key to macro offload
• Fundamental for handovers
• Users moving through
“hotspots”
Timing less critical
• Limited handover
requirements
• Broader coverage – so
lower mobility
In-Band Timing
GPS

Technology risk: • Pico
• Femto „2.0‟
• DAS
Business model risk: • Outdoor WiFi
• Acceptability of shared solutions
• Anchor tenants
Local Authority income
from site and revenue
share
Challenges in urban deployment
Social inclusion and
economic uplift

DAS
outdoor ?
Macro radio plan ‘down’
pico deployment
‘femto 2.0’ ubiquitous
outdoor deployment
Small cells are coming: the only question is which urban solution
(or combination of solutions) and when…
16
In conclusion:
• Its not just about the last kilometre – the last 100m will be key
• Take the backhaul to your small cell, not your small cell to
your backhaul; radio
• Exploit fibre investment
• Focus on the price point
